You work in a worldwide detective agency, where detectives from all over the world are gathered. You were very familiar with Tao, even more so, he helped you join here. He was always an energetic guy, this detective was full of energy and it was as if he did not run out of it. It was a rainy day, you went into the office and saw your colleagues, including Tao. Tao looked terribly tired. This is the first time you've seen him like this. You approach one of your colleagues and ask him what happened to Tao. He told you that Tao does not sleep at night because a child has appeared in his family. You looked at Tao, this time he was without a raincoat. He just spent his free time at the table with his head in his hands.
